For the first time, science and technology have taken charisma apart, figured it out and turned it into an applied science: In controlled laboratory experiments, researchers could raise or lower people's level of charisma as if they were turning a dial. You'll get both the insights and the techniques you need to apply this knowledge. The world will become your lab, and every person you meet, a chance to experiment.

Even the smartest among us can feel inept as we fail to figure out which light switch or oven burner to turn on, or whether to push, pull, or slide a door. The fault, argues this ingenious-even liberating-book, lies not in ourselves, but in product design that ignores the needs of users and the principles of cognitive psychology. The problems range from ambiguous and hidden controls to arbitrary relationships between controls and functions, coupled with a lack of feedback or other assistance and unreasonable demands on memorization.
